87MJJeep Posted September 19, 2007 Share Posted September 19, 2007 I noticed the vacuum line that runs from the air cleaner box to the valve that routes exhaust heated air to the intake was disconnected. With it disconnected, is it staying open to cold air? I thought I'd ask here before pulling it apart and seeing it it works when connected. Thanks!

DirtyComanche Posted September 19, 2007 Share Posted September 19, 2007 It doesn't do much either way. Disconnected it is closed, allowing the normal cold air in. IIRC. I thgrew it out WAY back. Link to comment Share on other sites More sharing options...

Thanks for the help. That is what I expected when it's disconnected. I'll leave that line disconnected. ;) Link to comment Share on other sites More sharing options...
